Overview
Comment:Relaxed the "enforcing" language around the planned change of hash policy from "auto" to "sha3" in Fossil 2.10 within section 2.8 of the fossil-v-git.wiki doc, and clarified what will actually happen with that release as compared to the current release.

to take, which amounts to the same thing.) But if you are a professional
software developer, we want you to ask yourself a question: "How do I
get paid more by mastering arcane features of my DVCS?" Unless you have
a good answer to that, you probably do not want to be choosing a DVCS
based on how many arcane features it has.

The argument is similar for other types of users: if you are a hobbyist,
how much time do you want to spend mastering your DVCSs instead of on
the hobby supported by use of that DVCS?

There is some minimal set of features required to achieve the purposes
that drive our selection of a DVCS, but there is a level beyond which
more features only slow us down while we're learning the tool, since we
must plow through documentation on features we're not likely to ever
use. When the number of features grows to the point where people of

repositories.

Here in mid-2019, that feature is now in every OS and package repository
known to include Fossil so that the next release as of this writing
(Fossil 2.10) will default to enforcing SHA-3 hashes by default. This


not only solves the SHAttered problem, it should prevent a reoccurrence

for the foreseeable future. Only repositories created before the
transition to Fossil 2 are still using SHA-1, and then only if the
repository's maintainer chose not to switch them into SHA-3 mode some
time over the past 2 years.

Here in mid-2019, that feature is now in every OS and package repository
known to include Fossil so that the next release
(Fossil 2.10) will begin using SHA-3 hashes even on repos currently
limited to SHA-1 for compatibility with Fossil 1.<i>x</i>,
effectively upgrading them to require Fossil 2.1 or newer. This
not only solves the SHAttered problem, it should prevent a reoccurrence
for the foreseeable future. With the current release (Fossil 2.9) only
repositories created before the
transition to Fossil 2 are still using SHA-1, and then only if the
